poor service

I went to kfc randburg square on the 24/12/2015, I stood in the line for about 10min because there was no cashier on site and the counters were dirty. I reported the matter to the call centre and I was told someone from the store will contact me within 48 hours. No one contacted me so I called the call centre again during the first week of January and till today I am still waiting for the store to contact me. I am unhappy with the service at the store as it is not the first time I am getting poor service. My reference number from the call centre is CAS-157304-G1Z1X5.
